WATER PUMP.

- Application filedrIuneLG, 1926. Serial No. 116,374.

This invention-relates generally to pumps used for pumping water and the: like,-'theinvention having mole particular. reference to a novel type of pump.

r Theinvention has for'an object thepro vision of an improved: pump of simple con structionand novel} arrangement of parts.

For further comprehension of the invention,. and of the objects and advantages in thereof, reference will-ibe haditofthexfollow ing' descriptionand; accompanying: drawing, and to the appended Clal1nS1n which the various novel features ofthe invention are more particularly set. forth;

Fig. 1, of the drawing,'.1s;a top pla-nview of my improved pump,partly in section: so

as to expose certain working. parts:

Fig. 2, is a side elevationalz view'thereof. Fig; 3, is a central sectional view of. the cylinder. head used in connection witlnmy. improved pump showing the valve cage at: tached thereto. i

Fig. 4., is a side elevational detail view of the valve cage.v V V As here embodied my improvedpump embodies cylinders 10 mounted on a suitable base 11. The piston 12, provided with piston rings 13, a slidablefit in the cylinder-10,.and having pivotally attached thereto; asat 14', by a piston pin, a piston r-od515,.pivotally attached as at 16, by apin, a connecting rod 17, pivotally attached,.as at 18, tothe'crank shaft 19; The crankshaft 19, is rotatively mounted insuitable bearings 20, attached-- E to the base 11. The pulley 21,.is rigidly attached to i the crankshaft 19,

The cylinder isprovided with a cap 22,

removably attached thereto, as at 23,. by bolts, studs, or thelike, and: is provided with an axial aperture-24, to slidably' accommodate the piston 15. s I

The cylinder 10 is provided with a cylinder-l1ead25, removablyattached thereto, as at 26, by bolts, studs or the like, and has suitably attached thereto an intake pipe 27, intercommunicative with the inner chamber, of the cylinder 10, and is also provided with a valve seat 28, tapered, or cone shaped, suitably formed therein.

The valve cage 29'is of hollow cylindrical constitution, provided with apertures 31, and having a closed end 30. The valve cage 29 is threadedly attached, as at 32, to the cylinder head 25, and islocated or positioned in the inner chamber of the said cylinder 10,

so assto'contain the ball 33, which is ofsuitable'diameter to closethe valveseat 28. c

The above described: construction being such. aswill; permit the piston 12.0fmy improved pump whenioperated. by a; belt, not shown in the, accompanying drawing, extendediover. the pulley 21 and over a second pulley attached to any; suitable prime-mover, not shown in: the 1 accompanying drawing, to draw in, or suck in:..water,, or any liquid, throughthe valve seat. 28,;and the apertures 31 of the valve cage 29, into the inner cham.-; ber of the'cyliuder 10,. on the'inward stroke of the saidpiston1-2, and;whichwillzpermit the-ball 33;,to engagewith orcover the; valve 1 seat 28,- on; the downward, or'return stroke of the piston 12., so as-to prevent the heretofore mentioned water, or liquid from enter ing the intake pipe 27. I

The cylinder 10 is provided with a valve seat '3 1,. tapered, or cone" shaped, suitably formed: therein, and, lo'cated,1or positioned adjacent to the cylinder headl25; The valve 1 I cage 35, of identical. construction "tothe above mentioned valve cage 29, is similarly.

to containthe ball 36, which is of suitable diameter tUiClOSB thevalve seat 34.

The cylinder 10,, has threadedly attached thereto, as. at 37, a suitable connection 38,. located. or positioned: over the valve cage 35, 1 and adapted. to suitably. receive an outlet. pipe 39, which may; be suitably connected,as at 40, by any desired fittings,.to a discharge pipe 11.

The later, described? construction, being such: as will permit. the piston; 12 of. myv im- I proved pump when: operated, asherein be- V fore setv forth,,to close the valve seat 34. 5 theball 36 engaging with or' covering the valve seat 34:", on thesaid inward stroke of. the piston 12, and: which will permit the ball 33 to disengage with, or uncover the valve seat 34, on the outward, or return stroke of the piston 12, so as to allow the heretofore mentioned water, drawn in or sucked into the inner chamber of the said cylinder 10, to be forced through, or discharged through the valve seat 34, the apertures 31, of the valve cage 35, the connection 38, and through the outlet pipe 39, and the discharge pipe 41. 7

It being understood that the discharge pipe 41 may be of any desired length, such no as may be required for irrigating. purposes, on farms, or the like. It being understood that I do not necessarily limit my improved device to this particular-purpose. It being further understood that myimproved device 7 may be used to pump any and allclasses of liquids, including acids, as my improved device may be constructed of suitable metal to withstand acids, or the like.

lVhile I have above described the pre' ferred' form, construction, and arrangement of the several elements employed, it will be understood that the device is, nevertheless, susceptible of considerable modification therein, and I therefore reserve the privilege of resorting to all such changes as maybe fairly embodied within the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new, and desire to protcct'by Let- States is as folters Patent of the United 1. In a pump of the class described, a cylinder having a circumferential flange on the bottom end thereof provided withspaced apertures,a valve member comprising a valve seat, circumferential flange on said valve member having spaced apertures therein adapted to register with the spaced apertures of said cylinder flange for attaching said valve memberto'the bottom of said cylinder, said valve member being provided with upper and lower screw threaded openings one on each side of saidvalve seat, a

ing provided with an opening having tapered fluid supply pipe screw threaded in said lower opening, a valve cage screw threaded in said lower open ng, and a ball disposed in said valve cage adaptedto rest upon said valve seat for closing the opening therein. A
